Nontoxic antimicrobial filters containing triclosan

Abstract

The present invention comprises nontoxic, environmentally friendly triclosan-containing antimicrobial filters composed of two layers, a filtering layer and a backing layer used to trap any triclosan released from the filtering layer. The filter media can be used in various applications including filter closures for facemasks.

1 .) A surgical facelet, comprising:
 a front layer impregnated with a quantity of triclosan for disinfecting a stream of air passing through said facelet; and   an air permeable backing layer disposed to receive air passing through said front layer, said backing layer containing a sorbent capable of scavenging any triclosan released from said front layer.
